Nominal Pipe Thickness specified in Dimensional Standards such as ASME B36.10M and ASME B36.19M includes following components : Theory Components of Nominal Pipe Thickness Then specify actual available plate/pipe thickness just more than minimum required R-pad thickness, to get width of Reinforcement Pad for the branch.
#How to calculate reinforcement pad dimensions trial#
Near exact size can be guessed by trial and error method when available area becomes slightly more than required area. If available reinforcement area A 2+A 3+A 4 is less than required reinforcement area, increase size of minimum R-pad thickness gradually. Start with 0 to check if reinforcement is required. Must be more than Minimum R-Pad Thickness entered above. *Enter Thickness of Plate/Pipe available to use as Reinforcement. Then increase gradually to make available area slightly more than required reinforcement area *Start with 0 to check if No-Reinforcement is OK. Type of Pipe Construction : Seamless, ERW or FBW for both Header and Branch.Negative mill tolerance for Header and Branch Pipe.Corrosion allowance for header and branch pipe.Nominal Pipe Size of Header and Branch.Material of Construction of Header Pipe and Branch Pipe.This calculator calculates branch reinforcement for Internal Pressure. This calculator works on the basis of criteria specified in section 304.3.3 : Reinforcement of Welded Branch Connections in ASME B31.3. Your comments and suggestions are highly welcomed. I have provided details of behind the back calculations at the bottom of this calculator.
